What causes stiff fruit in peaches?

The planting area of peach trees in China is very large, and when growing peaches, the phenomenon of stiff fruit often occurs. Stiff fruit in peaches means that the peaches stop growing before they are fully ripe, seriously affecting peach yield and planting profitability. There are many causes of stiff fruit in peaches, so what exactly are they? Today, the editor brings you several causes of stiff fruit in peaches. Let's take a look below!

1. Drought and lack of water

If stiff fruit occurs in peaches, a large part of the reason is insufficient water. Especially during the fruit expansion period, a large amount of water is needed. If drought and lack of water affect the fruit's water absorption, then the fruit will stop growing due to lack of water, resulting in stiff fruit. Therefore, when planting peaches, especially during the expansion period, we must pay attention to watering. Watering should follow the principle of frequent light watering. If watering after a long drought without rain, remember not to flood irrigate, otherwise the fruit is also prone to cracking.

2. Insufficient fertilizer

During the peach fruit expansion period, there is not only a relatively large demand for water, but also a relatively large demand for nutrients. If nutrients are lacking, then the peach fruit will stop growing due to nutrient deficiency and cannot meet the nutrients needed for peach expansion. In the growth process of peach trees, the demand for fertilizer also differs at different growth stages. During the expansion period, our fertilization should be mainly potassium fertilizer. According to the actual situation, apply it by flushing or spray foliar fertilizer to supplement potassium. Avoid peach fruit stopping growth due to nutrient deficiency, thereby causing stiff fruit.

3. Causes of pests and diseases

If the stiff fruit phenomenon in peaches is caused by insufficient water and fertilizer, then it generally affects a relatively large area. If only a few trees in the orchard have stiff fruit, then it is most likely not caused by insufficient fertilizer and water supply. It should be caused by pests and diseases. At this time, we should promptly identify the specific pests and diseases causing the stiff fruit in peaches. Then carry out targeted prevention and control. However, if it is within three weeks before harvest, then spraying is not allowed. Remove the stiff fruit in time to avoid the spread of the disease.

4. Causes of pesticide damage

When the area of stiff fruit is not large, it may be caused by pests and diseases. But it may also be caused by pesticide damage. When we use pesticides, if the use is improper, for example, if the pesticide concentration is too high or the amount used is too much. Then the harm to peach trees is very great, and it is not only prone to stiff fruit, but also prone to premature aging. Therefore, we must pay attention to controlling the amount of pesticide used. If it can be avoided, avoid it. When using it, be sure to pay attention to the concentration to avoid harming the growth of peach trees.

The above is a brief introduction to what causes stiff fruit in peaches. That is all for today's introduction. This article is for reference only, and we hope it can help everyone!
